CNPS list 1B includes plants that are rare, threatened, or endangered in California and elsewhere. CNPS list 2 includes plants that are rare, threatened, or endangered in California but more common elsewhere. CNPS list 4 is a watch list for species with limited distribution. SE: State listed Endangered, pursuant to California Endangered Species Act (CESA). SE designation includes taxa that are in danger of extinction throughout all or a significant portion of their range. SR: State listed Rare, pursuant to CESA. SR designation includes species that although not presently threatened with extinction are existing in such small numbers throughout all or a significant portion of its range that it may become endangered if its environment worsens. SC: Species of concern, includes species that may become candidates for listing or a species that DFG is considering to add to the list of Endangered species or list of Threatened species. FT: Federally listed Threatened, pursuant to the Endangered Species Act of 1973, as amended. FT designation includes species that are not presently threatened with extinction but are likely to become endangered throughout all or a significant portion of their range in the foreseeable future if special protection and management efforts are not undertaken. FC: Federal Candidate. FC designation includes taxa that require additional information to propose for listing. ST: State Threatened, pursuant to CESA. ST designation refers to species that are not presently threatened with extinction but are likely to become endangered throughout all or a significant portion of their range in the foreseeable future if special protection and management efforts are not undertaken. DFG: California Department of Fish and Game. N/A: not applicable, usually because the species has been delisted or not enough information is known about the species to designate a status but the species is still reported by the CNDDB.
